A) 2 p.m on Tuesday | B) 2 p.m on Wednesday |

C) 3 p.m on Thursday | D) 1 p.m on Friday |

Explanation:

Time from 12 p.m on monday to 2 p.m on the following monday = 7 days 2 hours = 170 hours

The watch gains min. or min. in 170 hrs.

Now, min. are gained in 170 hrs.

2 min are gained in hrs = 50 hrs

Watch is correct 2 days 2 hrs. after 12 p.m on monday i.e it will be correct at 2 p.m on wednesday.

A) 36 7/9 min | B) 32 8/11 min |

C) 34 3/11 min | D) 65 5/11 min |

Explanation:

55 min. spaces are covered in 60 min.

60 min. spaces are covered in min. = min.

Loss in 64 min. = min.

Loss in 24 hrs = min. = min.

A) 80 deg | B) 160 deg |

C) 140 deg | D) 135 deg |

Explanation:

As minute hand covers, 60 degrees

Minute hand covers 4800/60 = 80°

A) 3:16 7/11 | B) 3:16 11/4 |

C) 3:30 | D) 3:16 4/11 |

Explanation:

Coincide means 00 angle.

This can be calculated using the formulafor time A to B means ** [11m/2 - 30 (A)]**

Here m gives minutes after A the both hands coincides.

Here A = 3, B = 4

0 =11m/2 –30 × 3

11m = 90 × 2 = 180

m= 180/11 = 16 ^{4}/_{11}

So time = 3 : 16 ^{4}/_{11}

A) 10 : 27 : 41 AM | B) 8 : 51 : 04 AM |

C) 9 : 45 : 15 PM | D) 10 : 23 : 20 PM |

Explanation:

The watch gains 5 seconds in 3 minutes = 100 seconds in 1 hour.

From 8 AM to 10 PM on the same day, time passed is 14 hours.

In 14 hours, the watch would have gained 1400 seconds or 23 minutes 20 seconds.

So, when the correct time is 10 PM, the watch would show 10 : 23 : 20 PM

A) 90 degrees | B) 85 degrees |

C) 60 degrees | D) 45 degrees |
